One compact, one larger for mojo parts + one with switched transistors on Q3.
I tried so many different transistors fro Q3 it wasn't funny - I liked most of them and couldn't decide which one to choose, so I thought I would end up building a a few different MKIVs. Then I thought - why not put the transistors on a switch? Stole the idea from the Throbak Strange Master, but went for rotary. Signal runs from the Fuzz pot to the base of all transistors, with collector and emitters on the rotary switch.
